Lubuntu team has announced availability of Lubuntu 17.10 Alpha 1 for testing. This pre-release of Lubuntu will give a glimpse of upcoming stable release scheduled to release on October 2017.

Lubuntu 17.10 Alpha 1 ships LXDE as default desktop environment. Also, there is one experimental version of Lubuntu featuring LXQt desktop. It is not recommended to LXQt variation as it is highly possible to break.

Being a development release, Lubuntu 17.10 Alpha 1 is not free from bugs and a list of known bugs are available in official release notes. If you find any bugs other that listed in release notes, you can help Lubuntu by reporting it through proper channels.

Lubuntu Artful Aardvark Alpha 1 (soon to be 17.10) has been released!
Also in this release (in addition to the usual LXDE ISO) is an
experimental image with LXQt instead of LXDE.

We recommend that if you install Lubuntu Artful Aardvark Alpha 1, that you download the LXDE edition rather than the experimental LXQt ISO. The LXQt ISO will most likely break your system.
